Bluetooth Remote

PostThu Nov 15, 2018 12:02 am

I’m putting this out here, perhaps in the hope that Blackmagic might give this idea some thought and, given their manufacturing contacts and intimate knowledge of their product, they might just consider producing a Bluetooth remote.

Now what I mean by a Bluetooth remote is a hand controller that you can use in the hand or attached to a rig handle or the like. I’m not a big fan of mobile phone apps, as they simply introduce another device that you have to manage and watch for it to work, which means that you have to take your eyes and hand/s off your camera. And mobile phones aren't always that great to handle in these situations or in bright sunlight.

What I’d like is a simple controller that turns the recording on and off, and perhaps can adjust focus and aperture (lens dependent). When I’m using my rig and following a subject, using my follow focus, I really don’t want to take my eyes off the field monitor to especially turn on recording. A controller that could be attached to one of the handles on the rig (or anywhere convenient) and which simply connects to the camera when both are turned on and maybe can even be powered by a external battery would be brilliant.

Wireless remotes for stills cameras are a dime a dozen, but I suspect that something like this would be a long time coming for the BMPCC4K, if ever. When I think about it, even my Olympus LS-14 audio recorder has the ability to be controlled via an optical wireless controller:

Would anyone else find such a thing useful?

This device: https://www.newsshooter.com/2018/11/16/abelcine-cameogrip/ is kind of step in this direction, but unfortunately requires a cable connection. And it's also stupidly priced:

What I'm about to suggest takes it much further than just a simple start/stop remote, but you mentioned following a subject keeping focus, not wanting to look away and someone else mentioned needing something like this for a gimbal. Have you checked out the nucleus-m or nucleus-n? it is a FIZ with rec start/stop functionality. I haven't used the n, but I have the m and love it. I never have to take my hand off the handle.

I have heard of it and I just checked to refresh my memory. It's not really what I'm after and at US$1199 (https://tilta.com/shop/nucleus-m-wireless-follow-focus/) is more than what I paid for the camera.

What I'm after is a simple Bluetooth controller that, at most, would cost 1/10th of that and I'd be happy if it just turned recording on and off. When I'm recording, I'm looking at the field monitor and controlling focus using a follow focus wheel with my left hand and the pan/tilt with my right, so all I need is for my right hand to be able to start recording without me taking my eyes off the monitor.

But it is just a single follow focus, right? Nothing to do with start/stop recording from what I thought I’d seen.

B&H
It says in the question-answer section.

How does the Nucleus-Nano send a start/stop signal to the camera? What cameras is the start/stop signal compatible with?

Once you set up the motor and controller on your camera rig, you need to run an included camera-specific cable from the motor to the camera. You press "REC" to start recording and "REC" again to stop recording.

I believe it could be done through USB-C. But based on the renders, it appears Tilta is using Bluetooth.

What would be great, is if someone could create a LANC to USB-C adapter with a USB-C pass-through. No idea if something like that is possible though. LANC to USB-C should definitely be possible.

It would be the reverse of this:

I just played with the BMPCC4K Record Button app on my Pixel 3. Hands off for developing the app. It's still very buggy, but record and focus do work. But random things like iso changed when I pressed on parts of the screen that appeared blank. And couldn't figure out how to toggle between store and recall on focus presets.

Using a phone as a gimble remote is far from ideal. Gimble operation is a selling point of a small MFT format camera. I hope a proper gimble mountable bluetooth remote is in the works. The lack of gimble remote eliminates this camera from 50% of what I'd use it for.

Using a mobile phone app would be extremely awkward with a rig as well, even hand holding. When you're using a follow focus with one hand and controlling the rig movement with another and/or holding the rig in your arms while looking at a field monitor, there's no way that you could use a mobile phone at the same time.

An app might be handy when the camera is in a fixed position such as an interview, but even then it's another screen that has to be viewed. And if the screen constantly turns off (if it does this), that's another annoyance. Even when in a fixed position, a simple switch would be far more positive.

I don't know why everything has to have a mobile phone app. Years ago a simple mechanical cable release was enough for film cameras, now everyone wants a mobile phone app. Some even want their light switches to be controlled by mobile phone apps rather than a simple switch.

I've just reached over to my side draw to get one of these out. These VR/Game and camera controllers are like $5 or so dollars, very small, Bluetooth, and come with differing amounts of controls. My other one has more controls than this. However, maybe BM would like to make one with rocker switches and roller wheels for generic use. Would be useful in the wider market.

Under android you can program each button to do something different, though it depends on the app. I was going to use them to control mobile phone camera apps during filming. I was going to mount them for tripod work as well. Bluetooth, as USB does, will have device setup for multimedia controllers. So the camera might even have support built in already, or may need a firmware update. Please BM, a firmware update please?

Its a shame BM doesn't have a programming api for their cameras. They could just use JavaScript to use the api. Please BM, we could do the above and many little things which can latter be rolled into updates with fresh code.

Lets see now...

In the Pocket 4K manual there is Bluetooth and SDI control info for third party developers. The SDI seems to be there for the control messages that the Bluetooth also uses. Bluetooth uses/requires 6 digit pin for pairing (camera shows).

From messages on these forums the HDMI port supports start and stop record function, this is achieved by manipulating timecode on some cameras according to Atomos support web page.

There are some code samples available for other BM camera, should be mostly the same. The code samples are from/for Mac IDE.

...for "simple" Bluetooth controllers the camera would need to be able to do the pairing pin thingie.

I contacted Viltrox recently and asked them if they might be interested in designing a Bluetooth controller for the BMPCC4K. They came back to me yesterday and said they'd forward my enquiry to their boss. I let them know that the Bluetooth specs are available from Blackmagic, so no reverse engineering required. Viltrox makes some pretty good photographic gear, remotes lighting etc, so they might come up with something.

I did not get any such bug report from anyone and have no such issue myself.
Why didn't you report it, so I can find and fix that?
Please contact me via email with the details!

ISO should only be possible to change when pressing the ISO-slider in the "Settings: record" page.
The click area is the Android-standard 48dB and always slightly larger then the visible button.
(That's recommend by the Android Design Guidelines.)
Also "BMPC Record Button" is the very old name and indicate that it's a very old version of the app.
It has seen major improvements on a nearly daily basis in the first weeks.

My main gripe with a mobile phone controller is that you have to locate the phone somewhere convenient on a rig and then look at the phone to activate and deactivate recording. This is my rig, where do you put a mobile phone?

Image

Such a controller may work in some situations, but when you have one hand on a follow focus wheel and the other controlling the movement, you need another pair of eyes and hands to operate a phone controller.

That's why a simple on/off switch that you can hold in your hand, attach to the tripod handle or rig handle is so needed.

Yes, you are absolutely correct.
The screen timeout just a tiny detail that someone CAN do something about.

I did implement, that you can trigger the the camera from your Android Smartwatch.

I'm thinking of having my phone in the pocket.
The phone feeding LTC into the audio recorder on my shoulder rig and the camera.
Somehow rig the REC button on the right handle of my shoulder rig (currently LANC for the BMPCC)
to the phone and have my app send the start/stop(/playback) -command via Bluetooth.

There are "find my phone" keychain attachments that have a single button to take a selfie.
I could try to register for that intent and tell Android that my app is the preferred one to handle it
(so no chooser appears on the screen).... just a though at this point.

Given that there are simple Bluetooth devices (Bluetooth selfie sticks) that can trigger recording on a mobile phone, it should be a no-brainer to make a similar device to be able to trigger recording on the BMPCC4K.

The first out of the gate with one of these will sell heaps. And it could be applied to other cameras that use Bluetooth triggering technology. I would love to have something like that for my Olympus Tough TG5 that I use as a vehicle mounted action camera.

But the technology should be the same and Blackmagic provides the codes so that developers can produce complementary devices. The important thing is that it's not closed source where developers have to reverse engineer. That's what I meant with it being a no-brainer. For those that design such devices every day, it should be easy to make a device that connects to the camera.

The protocol description is public.
That's how I was able to to write the Bluetooth Android app.
The Bluetooth Low Energy layer still requires pairing and the camera won't accept 0000.
It needs the remote to send the random code that is displayed on the camera screen.
So whatever remote needs a user friendly way to enter that code.

So maybe you could connect the Bluetooth device to a computer to input the necessary code. Or the device could have a small screen. It makes the device slightly more complex, but still should be doable.

I already developed that for Smartwatches and will look into cheap selfie stick remotes.
I'm also already working on the starting an entire Multicam recording (nearly in sync) with a single button in the app.

Given that the protocol is Blackmagic specific, is it really necessary to have this layer of security? Why not just allow for bluetooth device selection from the camera without security check. If there are multiple camera operators within bluetooth range, hopefully they can coordinate and not both try to link to the same device...
Forcing the device to have a monitor limits the design and pushes up the cost

I can't believe Blackmagic hasn't either developed their own controller or partnered with someone to do it. Given that the Pocket 4K is selling like hot cakes, and they knew it would based on pre-orders and the success of the original pocket, having this cam launch without a working remote is crazy.

That security check is basic Bluetooth functionality.
Your bluetooth speaker, car stereo, wireless mouse,.. all do the same.
It has just become an accepted thing to have 0000 as a pairing code and a button
that must be pushed to allow a pairing to happen.

The service is in the camera.
The button is a client and can connect to as many camera as it can handle.
However without a screen I see no way to select what camera to connect to.

The devices use a standard protocol, the one I posted above allows many functions. But it's up to blackmagic to build in support for it. Firmware update.

You can turn the screen on permanently on android. It's in settings under display timeout, or in developer options after you enable that. However, you need a simple way to close the screen to save battery and open it again.

As far as finding space on the rig. You could use a $39 prepaid 3 inch phone, or iPod touch, and have an app with big buttons and controls.

HDMI CEC can pass a lot more than start and stop with it. It maps a remote, so may offer opportunity for up and down sets of controls by mimicking the butynd and directional pads on remotes.


However, with all these things BM.needs to build in support into firmware. This means setup menues to attach any hdmi or BT con role to a function. Could I suggest every mrnua function has options for mapping to hi cec and Bluetooth and USB at one time, so whatever yi plug in works. You define the key/control for a vanees control or menu function, and the vslye or rate of change. You also have the ability to save the configuration for each and to load in the configuration. That such devices can also download a configuration for that camera. So, you buy a device, and the camera during setup asks if would you like to load tje standard configuration for that camera, one of the other configurations if more then one on.the device, or set it up yourself, simple. The camera saves the configurations to it's memory, so you don't have to access them through BT again. Am I going too fast?

Re: Bluetooth Remote

I do understand that you can set a mobile phone screen to stay on permanently, but that then chews through the batteries, so in order for that not to happen, you then need to connect the phone to a camera rig battery (more cables). Bluetooth is low power so that won't be a big hit on battery power, but the screen will, as well as background activities, unless you have a separate phone with everything else disconnected (if possible).

But it doesn't really matter how big the activation buttons are on the phone screen, operating them will still be problematic as they won't be tactile and that means having to look at or fiddle with the screen every time. The attachment of the phone on a handle may also introduce issues because of the size and design of phones (even 3") and the need for larger holders. A Bluetooth remote with just a simple rocker switch for on/off would be far more functional and easy to use, muscle memory wold adapt very quickly like it does with a follow focus wheel.

Just on another note, for whatever reason, I always have incredible difficulty in getting touch surfaces to respond to my fingers. With any laptop touch pad, the response is always problematic and so I prefer to use a mouse. The same often applies to phone and tablet touch screens where I have to sometimes repeatedly touch or swipe to get any response from the touch surface. I'm clearly in the minority, but that's why I prefer mechanical controls.

A Bluetooth remote control with one or two physical buttons surely can't be such a difficult thing to produce.

Yes, that part of the comment was for people wanting to Mount a phone on their rig, and was a prepaid 3 inch phone with things else turned off (their apps for that). The big buttons were to compensate for small screen size. Yes, the battery life can last fur several or more hours with replaceable batteries. Yes, physical controls is better, bit people are talking about more than an on off switch so my little remote is perhaps better functionality.

Sticking with mounted use situations. With the little remote you get a multidirectional sliding controller pad, useful for focus and zoom, 5 buttons to turn things on and off, or select between different things the sliding pad controls (another idea for a firmware update basic scripting/macro) like focus, zoom, aperture, shutter, gain, iso, colours. The buttons could be assigned to be up and down on multiple functions. My other has more buttons, and you undoubtedly could probably find a dual directional control pad version with press firing switch on them. And maybe more buttons at the same time. However, if BM could do a filming version, that would be more useful. As then you. An customise placement hand for use and use thumb wheels and rocker switches.

I think there's room for both options, a simple on/off one and a more complex one. So far, all I've really wanted is an on/off controller. I preset everything on the camera screen and then it's just on and off, but I hate having to use the touch screen and the record button is inaccessible.

I agree, both. Live studio, live events filming, doco requires a bit of this. You can't just expect to maintain focus by maintaining distance doing doco and whatever helps male it easier and quicker. The pocket needs a lot of update, even to make as a descent stills camera with some non nonsense additional functionality. My local camera shop is staffed by industry guys, and they had the old pocket there shortly, but won't touch the 4k. They can't really sell enough of them, as they are not sellable to camera enthusiasts. But, if the had the features some would buy, but people would look down on the resolution is stills. So, a 6-8k (in coming future when cameras are normally that stills resolution) sensor version delivering 4k video would be sellable. 6k you can down scale, 8k you can use a quad Bayer sensor for 4k video, so you are using similar processing platform as now, for minimal redesign and cost increases.

Wrong thread. This is about physical, Bluetooth remote controls.

I think big issue is that this is not a camera for stills camera enthusiasts that want to dabble in video, it's a camera for cine enthusiasts that want to make films without the unnecessary things that hybrid cameras involve. I've mentioned elsewhere that I bought this camera specifically because it wasn't a DSLR/mirrorless camera that shot video. I have an Olympus E-M1 MkII that shoots 4K DCI video and found it anything but enjoyable for video (except in specific circumstances). This is where it does perform:



Sadly I still see new YouTube reviews, after the camera has now been around for nearly three months, lamenting the same lack of 'features' expressed from the beginning, such as that it doesn't have an EVF, it doesn't have IBIS, it doesn't have every other feature that's in say a GH5. So many don't seem to understand that this is not a stills camera. Even the stills button is not there for still image production.

And if you want to extract a still image from a clip, the ~9MP image is pretty good. In fact, I've seen some very large prints made from 4K stills from a GH5, so the quality isn't to be sneezed at. Mind you all too many stills shooters (who never photograph anything but their kids running around madly, ducks and brick walls) want 50MP FF cameras, else the camera is just a toy for amateurs.

Yes, marketing. Doesn't need to be less capable, but more. Gives them the extra sales and money to give better products, and do own sensors. The mini should be 16-17 stops with a sensor refresh

But again, the camera could do with updates to make physical controls easier, and this other stuff.

Sticking with mounted use situations. With the little remote you get a multidirectional sliding controller pad, useful for focus and zoom, 5 buttons to turn things on and off, or select between different things the sliding pad controls (another idea for a firmware update basic scripting/macro) like focus, zoom, aperture, shutter, gain, iso, colours. The buttons could be assigned to be up and down on multiple functions. My other has more buttons, and you undoubtedly could probably find a dual directional control pad version with press firing switch on them. And maybe more buttons at the same time.

So what’s the Deal? Is there no easy way to code a cheap remote? It’d be great to have a start stop button. And maybe the 3 custom function buttons too that are already mapped.then you could turn peaking on off easily etc

It doesn't look like anyone's interested in making one.

I'm taking a different approach and have ordered an old mechanical style cable release to see if I can adapt that to my cage to create a mechanical shutter release. Another option is to use a small solenoid where you can attach a momentary button anywhere convenient. I'm going to ponder the latter option as well.

I’ve been investigating this myself for the past week or so.

I recently got my Nucleus Nano and have been trying to figure out how I can take advantage of the start/stop functionality built into that system.

My plan is to build a LANC/Bluetooth device that will read in LANC commands and broadcast them over Bluetooth to the camera.

To do this I’m planning to use a really nifty little device called an ESP-32, and for those unfamiliar it’s a tiny microcontroller with both Bluetooth and WiFi capability. It’s small, doesn’t use a ton of power and is very cheap!

Image

Now I haven’t gotten very far with it yet, however I have been able to scan and see the pocket camera and attempt to connect. But that is where progress has come to a halt…. Establishing connection needs to be done ( as stated in the posts above ) using a pairing code and while that’s not necessarily a huge hurdle, I haven’t gotten the two to connect yet to a point where the camera will show the code on the back of its screen.

Image


Blackmagic does document this in their Developer SDK, but the libraries for this ESP-32 are relatively new and example applications like this are very few in number so I haven’t been able to work off of anything. Lot's of samples where making the ESP-32 acts a server for smartphone client, but really hard to find example where the ESP-32 is the client and its connecting to a server device ( the camera in this case )

Image

If any developers are out there with some advice or suggestions on how I can approach this next, that would be very appreciated!

And hopefully nobody treats you like the other guy was in that other thread.

Good stuff Csaba. You could look at the $5 camera controller/vr remote I mentioned also.

UPDATE. It now connects! 8-) :)

After some hours of fiddling with some examples, found a way to connect and do keyparing. After keypairing the device now automatically connects. Had to use my keyboard on my PC to enter the code via serial, but that’s a minor hurdle that can be addressed later.

Next Steps:
-Start/Stop recording on the camera from the ESP-32
-Read LANC Command from Nucleus Nano

Looking for some help understanding the Camera Control Protocol, those who developed IOS/Android apps if you can contact me via PM I’d like to discuss how I will implement the necessary camera control functions.

The developer documentation is actually fairly good and explains all things that LANC knows about fairly well.

You failed to mention that Csaba is attempting something that is within the bounds of reason and not making any demands on a manufacturer to ostensibly redesign a superseded camera. Maybe this is why you and a couple of others are having such a hard time understanding your problem.

That's excellent and given what you have been able to achieve, I'm hoping that some of the manufacturers that I've contacted may be on the same track.

Given that you can get one of these: https://tinyurl.com/yccha77w for AU$7.50, that does much the same, how difficult would it be to make one for the BMPCC4K?

Following! Interesting project.

If you need help in coding let me know. I'm busy with the SDI protocol found on the Ursa cameras, and have a lot of experience with protocols and conversions from 1 to a different protocol. ;)
